3 steps to save water leakage in domestic areas
Leakage is a key aspect of strategies to improve the efficiency and effectiveness of water supply services. Leak detection is a big priority to reduce water loss.
Filling the gap in the availability of appropriate materials and techniques on this issue means cities can save in reducing water loss from public water supply distribution networks and billions of dollars.
The fight for the reduction and control of losses is never ending but, fortunately for today’s water distribution engineers, a range of good equipment and techniques have been developed to assist him or her in tackling the four basic leakage management activities.
1. Leak detection
Placing meters on the pipe system to detect leaks. Acoustic loggers, surface sensor arrays, gas tracer methods and ground radars are used to define the general area (normally a DMA or part of a DMA) in which leaks are located and they can be used in any type of distribution network.
They are installed on pipe fittings by way of a strong magnet and are programmed to listen for leak characteristics. By recording and analyzing the intensity and consistency of noise, each logger indicates the likely presence (or absence) of a leak.
There is more
Using technology that is used to look for water on other planets, Utilis analyzes satellite imagery to detect leaks and non-revenue-water.
The result? Leak detection that covers thousands of square kilometers at once, and that can pinpoint a leak in a 6 meter radius area, saving significant labor associated with finding leaks with current tools.
2. Repairing the pipe
Most of the leaks and breaks are from cast iron pipes. The structure of cast iron changes over time as it reacts with soil and water. This causes pipes to break. The last 20 years, most of the pipes a made of a variety of ductile iron, steel and PVC pipes.
3. Prevention, water audits
By tracking soil moisture and rainfall patterns, water managers can predict where leaks are likely to occur. Also management program are using pressure reducing valves in high water pressure areas. This reduces water pressure and helps reduce the number of breaks and leaks in pipes. Inspection services and pipe monitoring allow operators to localize and pinpoint problems such as cracks, breaks,
